United A320 jumpseat DEN - SFO about eight years ago:
Get to cruise, 45-year-old-ish captain turns around and says, "So who do you work for?"
"Air Wisconsin."
"Never heard of them."
"Really? We flew for you for the last thirty years. We are literally the first code-share in history, United and Air Wisconsin. Until recently, United even owned us."
"Nope. Never heard of them. And I don't get it, why do you work there?"
"What?"
"I mean, why don't you just work here? I don't get why you guys go work at these no-name places."
"I'm sorry, are you serious?" I look at the FO who mouths I'm sorry.
This degrades into my needing to explain that there is a thing called the regional airline industry thanks to something called scope, and not all of us were so fortunate to get hired at United at age 23.
She never did get it.
